Barron, 21, was arrested in the Aug. 21 shooting of Kamar Allen, a Pasco County sheriff's report said. He previously had been charged in the Dec. 9 killing of 18-year-old Cedric Saunders of Holiday.

While in jail on the first charge, Barron told another inmate that Allen visited him at his home, 1037 Solar Drive in Holiday, the night of Aug. 21, the report states.

Barron had suspected Allen of stealing money from his mother and confronted him. The two later left the house on foot. Barron told Allen they were "going to go find some women," the other inmate said in the report.

In an open field between Anclote Boulevard and Blossom Lake Drive in Holiday, investigators say, Barron shot Allen and went home. Allen's body was found in a nearby ditch, four blocks from Barron's home, with a .40 caliber bullet in his head.

Allen's arrest record dates to 2010 with multiple charges of possession of marijuana and one charge of battery on a 75-year-old man.

Saunders, the victim in the Dec. 9 shooting, was found dead in a blue Kia Rio at Merrilon Drive and Wellington Drive in Holiday. Arrest reports said Barron told a witness he shot Saunders, too.

Barron was booked into Pasco County Jail in Land O'Lakes on Dec. 15 on several drug-related charges. He was booked again Dec. 22 in the murder of Saunders.

On Jan. 8, Barron was booked a third time when he was found in his cell carrying contraband items: a spoon he had sharpened into a knife, said sheriff's spokesman Kevin Doll.

When forensics reports came back from the Aug. 21 shooting of Allen, Barron was charged with a second murder.

Barron was being held without bail Monday at the Land O'Lakes jail.
